Dear brother,
Your videos are quite informative. Can you please explain how you have selected the value of B bar = 0 for undrained behaviour? Also, when you have simiulated full drawdown case the FS is 1.527 (Janbu) but in case of partial drawdown the FS is 1.17. What's the reason for that? Shouldn't the FS be lower in full drawdown then partial drawdown?

Sir it really helps me.... Thankx alot

[@user-vh6fd9zt8k]

Hi there, should the B-Bar value = 1 so that a changes in pore pressure in a material is directly proportional to changes in vertical stress?

[@eslamahmed7022]

Great brother

[@SuccessSpark099]

very informative sir

[@justforfunandmasti6527]

Good work keep it up 👍

[@GeotechwithNaqeeb]

I will try my best

[@MsAarju]

I understand that the water level will be the level of reservoir, but what about the phreatic line in the embankment? How do we find it in practical?

[@GeotechwithNaqeeb]

by pizometers

[@anasuyagoswami945]

Is it possible to generate phreatic line as an output parameter instead of drawing it as an input? Please help me

[@user-wf7ro9ek4z]

Thank you very much ...

B-bar is 0 or 1?

[@MsAarju]

How to find out phreatic line?

[@GeotechwithNaqeeb]

by pizometeric data

[@MsAarju]

​@@GeotechwithNaqeeb How do we get piezometric data even before the embankment is constructed?

[@malikrizwan3139]

We usually install series of piezometers across the embankment to continuously monitor the water levels. The elevation of phereatic line is determined from those piezometers.
